' Application filed March 8, 1915. Serial N 0. 12,868.

To (ZZZ whom it may concern Be it known that I, 12TH A. CRONE, a e tizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Brake- Beams, of which the following is a s eci- The invention pertains more particularly to trussed beams and especially toca, novel strut and connections for such beams.

In accordance with my invention-I pro-- vide a one-piece forged metal strut at one end receiving the compression merhber of the beam and at the otherend having se;

cured thereto a cap or socket of special configuration adapted to the tension memberand to strengthen the strut and aid in securing the two side members of the strut in due relation to each other.

The purpose of the invention is not only to provide a strut capable of being manufactured in one piece from forged metal, but also one which may be conveniently applied to position and be highly eflicient in use as well as durable for the purposes intended.

The invention will be fully understood from the detailed description hereinafter presented,reference being had to the accompanying drawings, in which:

Figure 1 is a vertical section through a brake beam taken along the edge-of the strut and therefore showing the strut in horizontal side elevation; Fig. 2 is a vertical transverse section through the same, taken on the dotted line 2-2 of Fig. 1; Fig. 3 is apv'ertical transverse section through a modified construction of strut, this section being taken through the strut near the outer end thereof 40 and the modification residing mainly in conveXing outwardly the sides of the strut and conforming the end cap or socket for the strut to receive such sides, and Fig.4 presents a suitable construction of cap for the outer end of the strut.

In the drawings, 10 designates the compression member,'11 the truss rod or tension member, and 12 the strut, this being formed from a single piece of forged metal folded at its center and extending transversely arfiiund and engaging the compression member 10 and carrying at the outer or free'ends of its sides a metal socket 13 adaptedrto receive and secure sn eh ends and also to engage the) truss rod it. The compression member 10 may 'vary in cross-seotion, but I prefer to 'use a ,channel beam for the member {10, as L'illustr'ate in Fig. 1.

The strut/l2 is, as shown, formed from a single bar of forged metal folded at its mid- 6Q dle portion to form a box-loop 14c adapted to encompass the outer s irfaces of the member 10,. whence the boy portions of the folded bar are correspondingly deflected to form the parallel angular sides 15 adapted .5 to receive between them in the usualmanner the customary btake' lever, not shown. The sides 15 extend parallel with each other to their outer or fre ends, and upon said ends is applied the ,cap or socket member 13,. which may bea malleable casting, a drop forging, or othermetal, having? at its outer end a groove 16 :to transversely receive the middle portion of the truss rod 11 and at its) inner portion a1; inclosingfiange 17 which receives the free ends of the sides of the strut and a filler section 18 adapted to fill in the space between the outer'ends of said sides, grooves being formed between said filler section 18fand the adjacent longer sides of the cap or socket 13.into which the outer ends of .the .sides'15 are securely held. The cap or socket: 153 on its longer sides is formed with sections =19 which engage the outer surfaces of the strut sides 15 and are parallel with the filler section 18. The cap or socket v 13 receives.betiween the sections 19 and opposite sides of the filler 18 the outer ends of the .sides 15 and finally said sides and said cap or socket are rigidly secured together by a rivet 20' passing through the cap or socket sections 19, strut sides 15 and filler 18; The sides 15 adjacent to the inner edges of the beam 10 receive between them a filler 21 througli'which and said sides extends a rivet 22, the latter with'the rivet 20 serving to secure the two sides of. the strut together and with tht filler parts 18 and 21, maintain said sides in due relation to each other. The

strut sides 15 are at a suitable point between the ends of the strut transversely apertured,

as at 23, tbreoeive the brake lever pin, not show and surrounding the apertures 23 are anges'24 pressed up from the material of the sides 15 to afford increased strength andj' a pnoper bearing for the brake lever pm.

L sha l preferably form longitudinal corrugations 25 in the sides 15 between the flanges ,24 and cap or socket 13, one corru- 110 gati onbeing formed in each side and con-- vexedtdutwardly therefrom, in the manner I indicate in Fig. 3 in a modification, so as to strengthen the sides 15 in their outer por tions which in use are under compression. The corrugations 25 may extend simply be: tween the flanges 24.- and cap or socket 1'), or they may continue, as 1 show in Fig. 3, into the end cap or socket.

Since Fig. 3 illustrates a modification ll number the sides of the strut 26, the corrugations in said sides 27, the end cap or socket 28, the filler contained in said cap or socket and extending between the strut sides 29 and the encompassing flange of the cap or socket 80. Fig. 3 is meant to illustrate that I may extend the corruga-.

tions 25 of Fig. 1 into the end cap or socket or omit to do so, as I may prefer, increased strength to resist compression being gained when the corrugations do extend into the end cap or socket. The cap or socket 28 is also illustrated in Fig. 4, and said cap or socket may be provided with eyes 31 to receive the usual suspension hanger.

1 preferably cause the boX loop member to closely bind against the compression member 10, and in addition it will be found desirable to additionally secure said box loop member to the compression member by means of a rivet 32, as shown in Fig. 1, the rivet extending horizontally through the outer member of the beam 10 and the metal portion of the outer member of the box loop 14-.

lhe essential features of my invention reside in the strut hereinbefore described in connection with the capor socket and other features referred to, the object being to, without undue Weight or Waste of metal, provide a truss beam construction having a forged strut of highly eiiicient and durahis character and capable of ready manufacture.

"What I claim as my invention and desire to secure by Letters Patent, is 2 l. A trussed brake-beam comprising a compression member, a tension member and a strut intermediate said members for the brake-lever, said strut being a folded bar having at its fold a box-loop encompassing said compression member whence the members of the bar are deflected forming angularly disposed parallel sides extending to the .outer end of the strut, and a cap-socket on the outer ends of said sides having a bearing for the tension member, sockets for the ends of said sides and means to receive rivet for securingthe cap-socket to said sides.
